What do you do when you don’t feel motivated to exercise?

I normally set aside the clothes one night before and have them ready so I don’t have to even think about what to wear. Sometimes I do exercise with my pijamas the 7 minute exercise. But I normally book a class in the gym and if you don’t go to the class you have to pay a no show fee that it is quite expensive. Therefore that helps me go and be there. Also I plan to go with someone then it is difficult to say no.
